CREAM-SEPARATOR.

Specification of Letters Patent.

To all unit/mt it 711.607 concern.-

Be it known that I, Hno'roR KIBELE, acitizen of the United States, residing at Bluffton, in the county of Allen and State of Ohio, have invented a new and useful Cream-Separator, of which the following is a specification.

This invention relates to cream-separators of the deep-setting gravity type wherein the milk is placed in a can surrounded by water for the purpose of cooling the same.

The principal object of the invention is to provide means for readily locking and unlocking the milk can and the water containing tank, so that the former may be readily removed for cleansing when necessary.

A still further object of the invention is to improve and simplify the construction of this locking and unlocking mechanism, so that in detaching the parts there will be but oneloose or disconnected member, so that the danger of losing any of the parts is reduced to a minimum.

A still further object of the invention is to provide means for compensating for wear of the parts, thus adding materially to the life of the apparatus and insuring at all times a thoroughly fluid-proof joint to prevent leakage of the contents of the water-tank.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanyingdrawings, Figure 1 is a sectional elevation of the lower portion of a cream-separator constructed in accordance with the invention. Fig. 2 is a similar view of a portion of the structure shown in Fig. l drawn on a larger scale. Fig. 3 is a detail perspective view of the gage-glass and its carrying-frame, being the parts supported by the milk-can and showing the same as protruding through the opening in the watertank. Fig. a is a similar view of the elontachable member of the device.

tratcs a slight modification of the locking mechanism.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In gravity-separators of the type forming the subject of the presentinvention it is usual to provide a water-containing tank and an inner milk-can, the latter carrying a gageglass and drawing-oif faucet that are arranged to extend through an opening formed in the wall of the water-tank, provision being made for insuring a perfectly water-tight joint around the walls of this openin The parts, further, must be so arranged that any person, preferably without the aid of tools, may readily loosen the joint and remove the milkcan for cleansing purposes. Many attempts have been made to provide devices of this character; but most of these are open to many objections, some requiring the use of wrenches, screw-drivers, and other tools, while in others the number of parts detached is such that there is always more or less danger of loss or breakage, so that the separator cannot be used until the missing parts have been found or replaced. There is, moreover, more or less wear on the parts, owing to the necessity of frequent cleansingof the milk-can and the locking and unlocking of the joint, the latter soon becoming loose and permitting leakage of the water.

In carrying out the present invention the watertank 10 is provided with a verticallyelongated opening for the passage of the parts carried by the milk-can 11. To the milkcontaining can is soldered or otherwise secured a plate 12, having a threaded opening 18 for the reception of a discharge cook or faucet 14, through which the contents of the can may be withdrawn as required. The wall of the can is provided with an opening in alinement with the opening 13, and above this is a vertically-elongated opening 15, that is in alinement with a small opening formed in the plate and carried by a transparent panel or gage-glass 16, which may be held in place by cement or putty in the usual manner. The panel 16 is seated in a recess formed by outstanding parallel flanges 18, which at their upper ends are enlarged to form a pair of spaced pivot-lugs 19, carrying a pivot-pin 20. On the central portion of the pin 20 is pivoted the inner end of a screw 21, that carries a thumb-nut 22, the screw and nut falling by gravity to a position against the face of the plate when the outer member of the connecting device is removed. At a point below the opening 13 the plate is provided with a recess 23, having an inclined or camlike outer wall 24, that serves to receive the correspondingly-shaped toe 25 of an approximately elongated clamping-ring 26.

The ring 26 follows generally the contour of the plate 12 and at its upper end is provided with an integral cross bar or head 27 which when in position forms a housing for the two pivot-lugs 19 and the inner end of the screw 21. The lower portion of the cross-bar is turned inward in the form of an obliquelydisposed flange 30, that is provided with a slot 31, through which the screw 21 may pass, while the outer face of the flange forms a clamping-surface against which the thumbnut presses in securing the outer clampingring in position.

It has been found that the greatest wear on the parts occurs between the lower portion of the clamping-ring and the inclined face 2 1 of the plate. To overcome this difliculty, the lower edge of the ring is provided with a threaded opening for the passage of an adj ustable screw 34, which may be turned in such manner that its point or inclined end engages against the cam-face 24 in place of the inclined tongue 25. This adjustment, however, will not be found necessary for considerable time after the apparatus has been placed in use.

hen the parts are in position for use, a

yieldable packing-ring 35 is placed between the outer portion of the plate and the inner wall of the water-tank, as will be seen more clearly on reference to Figs. 1 and 2. With the parts in the position shown in Fig. 1 it is merely necessary to loosen the thumb-nut until the nut and screw fall by gravity from contact with the flange 30, whereupon the outer clamping-ring may be readily lowered, or it will fall by gravity until the tongue 25 is disengaged from the cam-face 2 1. The plate 12 and faucet 14: may then be withdrawn'th rough the opening in the tank as the milk -can is drawn back. The only loose part, therefore, is the elongated ring 26, and this is of such a size that it cannot be readily misplaced. When the milk-can is again placed in position, the ring 26 is adjusted and the clamping-screw is ter-vessels of diflerent shapes and sizes and arranged to contain more than a single can.

Having thus described the invention, what is claimed is- In apparatus of the class described, the combination with the inner and outer vessels, of which the outer vessel has an elongated opening, a plate secured to the inner vessel and having a portion projecting through said opening, a transparent panel and a faucet carried by said plate, the lower end of said plate being provided with a recess having an inclined wall, a pair of spaced pivot-lugs arranged at the upper portion of said plate, a pin carried by said lugs and extending transversely of the plate, a screw mounted on said pin and free to fall by gravity against the face of the plate, an elongated clamping-ring adapted to surround the projecting portion of the plate and having at one end a cam-tongue for engaging the inclined wall, the upper end of the ring having an integral cross bar or plate, which, when in position, forms a housing for the pivot-lugs and the inner end of the screw, the lower portion of said cross-bar being extended inward in the form of an obliquely-disposed flange having a slot for the passage of the screw, and a thumb-nut carried by the screw and bearing on said obliquely-disposed flange whereby the ring is forced tightly against the outer face of the outer cam, and the camtongue at the lower endof the ring is pressed forcibly in engagement with the inclined wall of the recess, substantially as specified.

In testimony that I claim the foregoing as my ownI have hereto affixed my signature in the presence of two witnesses.

HECTOR KIBELE.
